how to solve momentum problems

welcome students this is a small

tutorial on momentum what is momentum

momentum is defined as P to MV since

velocity is a vector quantity momentum

is also a vector quantity so if we know

the mass and velocity we can calculate

the momentum easily the moment of the

system particle is equal to Vector sum

of the momentum of the objects within it

the change in moment of body is equal to

force applied to time taking that is P2

- P1 = to Ft where F denotes of force

applied and T is the time taken let us

take a small question on this a golfer

hits a golf b ball of Mass 2 kg the ball

leaves the club with a velocity 10 m/

second the ball and Club remains in

context for 006 second we have to find

two things here find the average force

exerted by the club on the ball find the

ball's final momentum in these type of

questions first we need to get a clear

picture of double here the ball is hit

by the club and it moves so here the

change of momentum is due to for exerted

by the club on the ball so from impulse

formula we can say that ft = to P2 - P1

F need to be calculated time taken is 06

and initial momentum is zero the final

momentum is P2 is 2 into 10 so F equal

to 666 M Newton now final momentum is

given by P2 = to MB M is2 and velocity

is 10 to it's 2 kg m/s for more tips and
